A large slip blocking access to Wellington from western suburbs will close the road for several days.
Workers are attempting to stabilise and clear a large landslip on Ngaio Gorge Rd.
The landslide has grown significantly overnight since the first material came down off a steep bluff and closed the road early on Saturday morning, said Wellington City Council spokesman Richard MacLean.
"The road is now completely covered by large boulders and rubble."
